Article Synopsis
- The study aimed to create a prediction model for lymph node status in T1b esophageal cancer and identify key predictors for squamous and adenocarcinoma types.
- An analysis of 2098 patients from 37 studies showed significant percentages of lymph node and vascular invasion related to histologic differentiation and submucosal invasion levels.
- Predictors of lymph node positivity varied by histologic type, with sm3 invasion and vascular invasion being crucial for squamous cancers, while lymphatic invasion was the main predictor for adenocarcinomas, highlighting the need for tailored surgical management.
Risk of lymph node metastasis in submucosal esophageal cancer: a review of surgically resected patients.
Expert Rev Gastroenterol Hepatol

Objectives: Endoscopic local procedures are increasingly applied in patients with superficial esophageal cancer as an alternative to radical oncologic resection. The objective of this article is to determine the risk of nodal metastases in submucosal (sm) esophageal cancer, comparing the two predominating histologic tumor types, squamous cell cancer (SCC) and adenocarcinoma (ADC).
Methods: A query of PubMed, MEDLINE, Embase and Cochrane Library (1980-2009) using predetermined search terms revealed 675 abstracts, of which 485 full-text articles were reviewed.
